While their charms are lost upon me (I’m a chocolate milkshake, preferable made using mint chocolate chip ice cream, but that’s another story,) vanilla milkshakes are the most popular flavor in the world.
An important fact to know is that the first known printed reference to a “milkshake” dates back to 1885. It contained one part whiskey, ‘for medicinal purposes’. A prescription your old pal the doctor would be happy to fill for you. Milkshakes got their name from being served in bars. If the customer enjoyed the specialty drink, he shook hands with the bartender. If not, the bartender wouldn’t get a tip.
